There are also guys like Adrian Wilson, Abram Elam, DLandry, Bigby that can play SS well... Plus, some of what Quin did this year was a result of a lack of coverage ability at LB. Cushing's health and the addition of someone like McIntosh, Akeem Jordan, Boley, M.Lawosn, Keith Rivers, or Dansby could change the need for a safety that can play in the box. By the way, in today's NFL, I'd much rather deal with two safeties that struggle to plug the run than safeties that can't cover a tight end.

Your right but....Adrian Wilson turns 33 in October, Elam turns 32 in October, and Landry turns 31 in December but I do like him. Atari Bigby has been dealing with injuries his entire career and turns 32 in September.

None of the linebackers mentioned can be expected to cover slot receivers and TEs.
